I disagree. I'd think that the chapter would have to be the one to initiate the paperwork involved in change of membership status.

To the OP, as you can see, there are differing opinions here. I'd still consult with your EC because they're your closest resource. Start with your chapter advisor, and she'll know who to direct you to. I'm thinking VP Membership and/VP Finance (or whatever your sorority calls them).

How long have you known about this co-op? Did you just find out or did you know for a while already? I only ask because of the deadline RaggedyAnn mentioned.

We had several girls study abroad over the years, and they still had to pay dues (a lesser amount). But again, each sorority handles their membership differently, so please talk to your EC ASAP.
